定义枚举接口

public interface BaseEnum {
    /**
     * 获取枚举值
     * @returnint
     */
    Integer getValue();

    /**
     * 获取枚举名称
     * @return
     */
    String getName();
}

枚举类

@Getter
public enum TestEnum implements BaseEnum {
    TEST1("name1",1),
    TEST2("name1",2),
    TEST3("name1",3);

    private String name;
    private Integer value;

    private TestEnum(String name,Integer value){
        this.name = name;
        this.value = value;
    }

}

获取所有枚举

    public static void test4(){

        Reflections reflections = new Reflections("com.xxx.modules");

        Set<Class<? extends BaseEnum>> monitorClasses = reflections.getSubTypesOf(BaseEnum.class);

        System.out.println("size:"+monitorClasses.size());
        monitorClasses.forEach(m->{
            try {
                System.out.println("name:"+m.getSimpleName());
                BaseEnum[] enumConstants = m.getEnumConstants();

                for (BaseEnum anEnum : enumConstants) {
                    System.out.println("enumName:"+anEnum+"  value:"+anEnum.getValue()+"  name:"+anEnum.getName());
                }

            } catch (Exception e) {
                e.printStackTrace();
            }
        });
    }

输出

需求：定义了一个枚举类，枚举类里面的参数需要返回给前端
当然这里既然是枚举出来的，一般不需要轻易改动，前端也是可以写死的
废话少说上代码

/**
 * 自然人客户证件类型
 */
public enum IdCardTypeEnum {
    sfz("111", "身份证"), hk("112", "户口簿"), jrz("113", "军人证"), hz("114", "护照"),  jdc("115", "机动车驾驶证")
    , gatxz("116", "港澳通行证"), dltw("117", "大陆居民往来台湾通行证"), gajm("118", "港澳居民来往内地通行证")
    , twjm("119", "台湾居民来往大陆通行证"), wgr("120", "外国人永久居留身份证"), qt("999", "其他");

    private final String code;
    private final String message;

    IdCardTypeEnum(String code, String message)
    {
        this.code = code;
        this.message = message;
    }

    public String getCode()
    {
        return code;
    }

    public String getMessage() {
        return message;
    }
}

我想要的是将Code与message返回给前端做选择参数

@RestController
@RequestMapping("/third/ins/zxb")
@Slf4j
public class ZxbController extends BaseController {

	@GetMapping(value = "/param/{type}")
    public AjaxResult param(@PathVariable("type") String type) throws Exception {
        Class<Enum> clazz = null;
        try {
            // 参数转大写
            String className = type.substring(0, 1).toUpperCase() + type.substring(1);
            // 通过完整的类名获取
            clazz = (Class<Enum>)Class.forName("com.third.ins.constants.zxb."+className);
        } catch (Exception e) {
            return AjaxResult.success();
        }

        //获取所有枚举实例
        Enum[] enumConstants = clazz.getEnumConstants();
        HashMap<String, String> hashMap = new HashMap<>();
        for (Enum enumItem : enumConstants) {
            String code = clazz.getMethod("getCode").invoke(enumItem).toString();
            String message = clazz.getMethod("getMessage").invoke(enumItem).toString();
            hashMap.put(code,message);
        }
        return AjaxResult.success(hashMap);
    }
}

最终返回结果：
